What I see here, is chaos. I see meteors flying towards them, a fiery inferno, and storms. At the base of all this is a couple, comforting each other in their last moments before death. Touching? A bit, but also a bit cliche...like a typical movie ending.
The art is very good, I only noticed a few things I don't like about it. The girl looks like a cyclops, and the guys arm is deformed. Might wanna polish up on drawing biceps/triceps lol.
Other than those minor things, a great image. The background has a very chaotic feel to it, and that sun looks daunting. I think you did a great job on conveying that.
Keep up the great work.
